1. What happens with the passing years?

Sagot :

Final answer:

The process of aging involves diverse biological, cognitive, and psychological changes that vary across societies and over time.


Explanation:

The perception and experience of aging vary from one society to another and within a given society over time.

Biological changes certainly occur as we age. The first signs are probably in our appearance. Our hair begins to turn gray, our (male) hairlines recede, and a few wrinkles set in. The internal changes that often accompany aging are more consequential, among them being that (a) fat replaces lean body mass, and many people gain weight; (b) bone and muscle loss occur; (c) lungs lose their ability to take in air, and our respiratory efficiency declines; (d) the functions of the cardiovascular and renal (kidney) systems decline; (e) the number of brain cells declines, as does brain mass overall; and (f) vision and hearing decline.

Cognitive and psychological changes also occur. Learning and memory begin declining after people reach their seventies; depression and other mental and/or emotional disorders can set in; and dementia, including Alzheimer's disease, can occur.
